Hot up to 450 ° C. A copper ball weighing 100 g cools down to 50 ° C. How much heat does it generate?

Problem data: t1 (initial temperature of the taken copper ball) = 450 ºС; m (mass of a copper ball) = 100 g (in SI m = 0.1 kg); t2 (end temperature) = 50 ºС.

Reference values: Cm (specific heat of copper) = 400 J / (kg * K).

The amount of heat that a copper ball can release is calculated by the formula: Q = Cm * m * (t1 – t2).

Let’s calculate: Q = 400 * 0.1 * (450 – 50) = 16,000 J.

Answer: When cooled, the copper ball will release 16,000 J.
